NOTICE
Using anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.
Leather (if equipped)
• Features of seat leather -
Leather is made from the outer skin
of an animal, which goes through a
special process to be available for
use. Since it is a natural product,
each part differs in thickness or
density.
Wrinkles may appear as a natural
result of stretching and shrinking
depending on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.

- The parts contacting the body are
curved and the side supporting
area is high which provides driving
comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
CAUTION
• Wrinkles or abrasions which appear
naturally from usage are not covered
by warranty.
• Belts with metallic accessories,
zippers or keys inside the back
pocket may damage the seat fabric.
• Make sure not to wet the seat. It may
change the nature of natural leather.
• Jeans or clothes which could bleach
may contaminate the surface of the
seat covering fabric. • Caring for the leather seats
- Vacuum the seat periodically to remove dust and sand on the seat. It
will prevent abrasion or damage of
the leather and maintain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protector may prevent abrasion of the cover and
helps maintain the color. Be sure to
read the instructions and consult
a specialist when using leather
coating or protective agent.
- Light colored (beige, cream beige) leather is easily contaminated and
the stain is noticeable. Clean the
seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack.
• Cleaning the leather seats
- Remove all contaminations
instantly. Refer to instructions below
for removal of each contaminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet cloth
and remove water with a dry cloth.
- Beverages (coffee, soft drink, etc.)
Apply a small amount of neutral
detergent and wipe until
contaminations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
- Chewing gum Harden the gum with ice and
remove gradually.

Cleaning the seat belt webbing
Clean the belt webbing with any
mild soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the soap.
Do not bleach or re-dye the webbing
because this may weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become hazy (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass cleaner
container.

Do not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster
grid.
